A 1/10th of a second watch from Patek is ... not realy Pateklike.
And to place that property on the dial is cheap, sorry.
Also, all the effort to fix an (unneeded) task/problem with such amount of engineering is the Lange way, something Lange is known for.
Teeth of a hight of 30 micrometer can't be longliving parts of this watch, if frequently used.
The price is beyond good and evil.
And to finish it: a correct scaling of theire incorrectly scaled chrono dials would have done the trick, too.
I am not really a fan of this watch ...
